CASE FOR UNIVERSAL JOINTS.

To all whom it may concern: Be it known that I, PAUL G. BnNNnrr, a

citizen of the United States, residing at vversal Joints, and declarethe following to be a full, clear, and exact description of the same,such as will enable others skilled in the art to which it pertains tomake and use the same, reference, being had to the accompanyingdrawings, which form a part of this'specification. y

This invention relates to a case for universal joints and its object isa universal joint so constructed in relation to a transmission case orother-oil reservoir vent leakage of oil therefrom. Another objectof theinvention is a universal joint which is automatically oiled by theleakage from the transmission case: These and other objects and theseveral novel features of the invention in its preferred formarehereinafter more fully described and claimed and shown in theaccompanying drawings in which Figure 1 is a longitudinal section of theuniversal joint showing part. of the transmission case contiguousthereto.

Fig. 2 is an elevation of the universal joint.

Fig. 3 is a section of the universal taken at a right angle tofFig. 1.

Similar characters refer to similar parts throughout the drawings andspecification.

As is usual in this type of device a main drive shaft 1 is providedwhich extends through the transmission case or oil receptacle and iskeyed to a flange 3. The proeller shaft 2 as shown more particularly inig. 1 is keyed to the part 4 of the universal joint which in turn ispivoted to the part 5 joint of the joint, the part 5 of the joint beingpivoted to the flange 3. A guard 6 is provided bolted to the flange 3 onthe outer edge thereof, the inner edge of the guard 6 being flangedinwardly and provided with a packing 7 on each side thereof and adaptedto be held tightly in place by the gland 8 which binds against thepacking 7 and 9 when drawn up and, as is shown in cone shaped oil babearings 10 about the sha A cup shaped plate 11 is provided as inSpecification of Letters Patent. r

as to pre-' the common practice.

Fi 1 the transmissioncase is provided with 1.

the .Well known types of universal;joints and is bolted to the flanges12 and 3, the flanges 12 and 3 being apertured at 1 about thecircumference" thereof for a purpose hereinafter stated. As will benoted more particularly in Fig. I the plate 15 is pro vided with aflange 18- which fits about the part 4 of the universal joint and aspring 16 tends to hold the pac 'ng 17 in engagement with the cup shapedplate 11 and by thistension'of the spring 16, it can beseen the packing17 will tightly contact the cup shaped plate 11 at different pellershaft 2.

In the common type of universal joint the oil from the transmissionworks along the shaft 1 and thus leaks out of the transmission case asmay be seen on the under side positions of the proof the floor boards ofan automobile which becomes spattered with oil. The object of thisinvention is toprevent this waste of oil and use itto automatically oilthe universal joint bythe oil working along the shaft 1, until it passesinto the interior of the joint. In this device the oil in working alongthe shaft 1 passes the gland8 and is thrown outward by centrifugal.force and thus contacts the sides of the guard plate 6 and is forcedalong the sides of the 'plate 6 to the apertures 14. Upon lpassingthrough the apertures 14 the oil wi tend to collect on the moving partsof the joint and thus oil it. To prevent leakage of oil the packing 7-.is provided about the iflange on the plate 6 and the packing 17 isalso provided- I on the inside of the joint to prevent leaka e of theoil by centrifugal force which mig t take place if the plate 15 andpacking 17 were placed on the outside of part 11 as is Thus it can beseen that this'type of universal joint prevents oil waste and uses theoil that would naturally be wasted to lubricate the joint.

From the foregoing description it becomes evidentthat the device, whileof a sim le nature, by adding the plate 6, the nut 8 and conti'g-. uouspackings and by boring the holes 14 in the respective plates the commont s of universal joints may be made self-lu ricatin and thus preventwastage of oil.

aving thus briefly described my invention, its utility and mode ofoperation what is very efficient in operation and t at w oil escaping Iclaim and desire to secure by Letters Patent of the United States is v1, In a device of the character described, the combination with a shaft,and a bearing therefor adapted to be supplied with oil, of a universaljoint structure secured to said shaft and comprising a laterallyprojecting member mounted on said shaft and having an oil passagethrough it, and a casing inclosing the space between said laterallyprojecting member and said bearing, whereby from the bearing is causedto pass through said oil passage into the universal joint structure.

2, In a device of the character described, the combination with a shaft,and a bearing thereforvadapted to be supplied with oil, of a universaloint structure secured to said shaft and comprising a laterallyprojecting member mounted on said shaft and having an oil passagethrough it, and a casing in closing the space between said laterallyprojecting member and said bearing and carried by and rotating with theuniversal joint, said casing arranged to confine oil escaping from saidbearin and to cause such 011 to pass through sai oil passage into theuniversal joint structure.

3. In a device of thecharacter described, the combination with a shaft,and a bearing therefor adapted to be supplied with oil and a packingarrangement comprising a gland, of a universal joint structure securedto said shaft and comprlsing a laterally projecting member mounted onsaid shaft and having an oil passage through it, and a casing innaaenclosing the s ace between said laterally pro structure.

4. In a device of the character described,

in combination with ashaft, a bearing therea for, a gland about theshaft having a flange thereon, a universal joint, a casing securedthereto, a flange at one end of the casin adapted to fit between theflanged gland and the bearing and packin about 'the'flan e on the casingto prevent Ie from, the casing providing a means for conveyin oil fromthe bearingto the joint.

5. n a device of the character described, in combination with a shaft, abearing therefor arranged to be supplied with oil, a universal'jointhaving'one member attached to the projecting endof the shaft, saidmember beingrovided with a flange, a two-part casing inc osing thejoint, the two parts being secured to opposite sides of and near theperiphery of the flange, one part extending akage of oil t eretoward andinclosing the end of the bearing. 3

for the "shaft, the other part inclosing the joint, the flange beingapertured to allow oil on one side to. pass from the compartment of theflange into the compartment in which I the joint is located.

In testimony whereof I sign this specification.
